I always have clear space ahead.

Agas are not JUST cookers. They are heaters of a certain character as well.

I don't deny they have character. I have owned many devices with
"character" over the years and been very glad to see the back of most
of them.

It is simply ridiculous to compare running costs with a gas cooker.

If you buy them for their looks or as a status symbol or for any
other reason unrelated to cooking you are absolutely right.

6500 is a fair price for an installed CH sytem let alone adding a cooker on
teh price :-)

If you got an installed central heating system as well as an Aga for
that price you would be right.

I do, but I believe my own experiences and have had run ins with those who
don't believe me. That's their problem.

Interesting though that they then expect us to believe what they say which
is based on their own experience ...

Cooking between 1 and 3 meals per day from basic ingredients does not

Of course it isn't, I do it. But that's just my experience so it must be

That was true of my old eye-level oven but that had lots of space above
it behind a grille. My new under-worktop built in oven has a fan to
circulate hot air round the oven itself and a second fan that draws air
over the casing and out the front. The latter keeps running for some
while after you turn the oven off.

S'obvious really! Also a normal cooker is much more practical and
versatile than Rayburn/Aga etc. If you really like the "Aga" style of
cooking then you can mimic it easily on a normal cooker - but without
having to buy special pans etc. Not sure why you'd bother however.
The good news is: you can probably sell it 2nd hand and get most/all of
the price of a proper cooker.

Interesting thread this. To get back to the start and answer the OPs
query: thought I would add to my first thoughts - all the above I
would still say, but I would add - "on the other hand by all means keep
the Rayburn if you really really want to as a few people seem get
really hooked on them and you too might appreciate whatever it is they
get out of them inspite of the high running costs (but I can't see it
myself!)".

Nope. All the fan blown ovens I have had generate a hot draught out of a
vent somewhere.

Are you suggesting that fan ovens discharge the hot air from the oven
into the surroundings? I don't think so. I only have experience of
one fan oven and it certainly does not discharge hot air into the
surroundings. If it did why wouldn't the surroundings (kitchen)
temperature tend to rise to the temperature of the oven and the
kitchen be filled with oven fumes? What is wrong with this equation?

I certainly get steam coming from the grille at the back of my cooker when
the fan assisted oven is on. It's not sealed.

But I get a lot more from the door opening when I open the door, presumably
because it's being blown out :-)

There was always some steam from my gas oven when I had one, there was an
opening on the hob to allow it to escape. It's no bigdeal, is it? I don't
wantmy oven cooked food to be steamed or pressure cooked.

But what energy costs? Agas are MORE efficient than CH boilers.

That's complete nonsense, surely? How can an open-flued non-condensing
appliance possibly compete with a modern condensing gas boiler?

Quite easily. It uses a long flue path to extract the heat down to an
effkux temperature up the flue of about 35C.

With CH water running at higher than that, even in a codensinng boiler,
more heat has to go out of the boiler flue than the aga flue.

The ONLY thing that marks boiler efficiency is how hot the exhaust gases
are when they leave the house and go through the insulation.

WRONG. It's also the volume and composition of exhaust gases (latent
heat), plus losses to the heated space caused by any ventilation
required by the boiler.

Do Agas condense water out of the exhaust gases to recover latent
heat? I think not!!!

Plus the required vent (sized for worst case operation) and the
required draught diverter do a nice job of draining warm air out of
the room, THAT is why the exhause gases are cool!

Pete.

Not since they built the new bit with Primark in. Rumours of feral

far unconfirmed.

So far as I know they have been spotted in Mattelan in Coatbridge

Oh indeed it does, all bad - and I look forward to the day when I can
either modify it to make it more efficient and give it a suspension
system or trade it in for something with suspension.

Its great advantage is partly artificial, nulabor has decided it
needs neither an MOT nor road tax which given the small mileage it
does is very useful and partly that there is no practical
alternative. I occasionally need to move bulky and heavy objects
locally. The purchase and running cost of my milk float makes it
very much cheaper than any other alternative. It is also a pig to
drive. Given my requirements this latter deficiency is (just)
acceptable.

I'm surprised they don't have suspension.

I always thought that the point of an electric milk float was so that
they can go around in the wee small hours without waking people up.
However, with no suspension, one would think that the bottles would
rattle.

Hmm. This thread is quite intriguing. We have various MEN arguing about
the merits( or otherwise) of cooking in a particular manner. When do
these people find time to do any real diy? Cooking is for women, it's
something some of them do really well, particularly when they know their
place in the scheme of things.

Incidentally, I always understood that traditional Yorkshire non suet
puddings were stodgy, is it only in recent years that they have become
crispy and light? The suet pudding I used to get in Yorkshire was always
totally solid, not a scrap of air in the pastry, I was informed that
this was the correct way to build up a reasonable waist line to allow
lots of hard work. I write only as a food consumer. LOL

Personally I know of very few men(thinking more about it, NONE) who
cook even one meal a day from basic ingredients. A few women may do so,
but only on occasional days. After all, this is why the fish and chip
shop was invented, together with all the modern derivatives.

I am not an Aga person, I find them warm to stand beside in winter, but
a bit of a pain to use in the real world. Rather like the coal fired
stoves of my childhood. ( Which were a definite fire hazard to small
children as I can testify from family history.) However, if you do want
one of these objects, buying one second hand can be a good economic
proposition, with a few years of inflation, you can then sell it on to
another mug and probably show a profit. Progressing to buying a proper
cooker with an eye level oven and grill, and not a style, I would regard
as a sign of great experience and maturity.

Capitol

Mine has suspension -- whacking great leaf springs -- but no shocks,
which I suspect is what Peter meant. It does make tackling "traffic
calming" an interesting enterprise.

They *are* taxed, but at a rate of £0.00. You can drive them on a normal
licence and my insurance is around £40 (TPO, but allows for 7 passengers
and 3 drivers).

All they have is a set of leaf springs (no dampers) which move about
an inch when 3 ton is put on the back.

They have a tax disc - but it is issued free, much to the confusion
of many post office staff.

What kind of licence do you need and what about insurance?

Car licence and fully comprehensive insurance is about GBP70 per
year. The combination of a need for short and infrequent journeys,
the type of load and the very low standing cost make it ideal.

I actually did some tests on the aga with an oven thermometer.
Wih all hobs closed it was about 210C.

After an hours cooking on both hobs, it was 195C.

7% drop.

Its an oil fired aga with thermosat controlled burner.

What this shows is that

- yes, flat out it cannot maintain oven temp with both lids up but
- since it takes 4 hours to heat up, even with no burner on, it probably
takes 4 hrs to cool down..and an hours hob cookng with a modulating burner
is not really going to affect cooking temps enough to be noticeable.

I THINK the oil flow rate on 'full' is about 3x what it is on 'low' which
implies that its probably only about 1.5KW into the ovens, max. As I would
assume that 'low' oil flow is less than what it does at 'idle'

I've measured the gas one and it's able to regulate even more tightly
than the 7% that you got..
